Intro
Now, normally, this would be a “foldable vs bar phone” debate. But the Fold 7 is rumored to be catching up in the camera field and slimming that design, making it less of a compromise and more of a “the best of everything” phone. As it should be, for $1,800 (hopefully, not more)! Meanwhile, the S25 Ultra is built on multiple refinements and reiterations of the same tech. If you follow it back to its roots — it’s a Galaxy Note. Just made 47 times better with modern tech!
Two flagships. Two philosophies. Only one pocket. Let’s see who fits best.
Galaxy Z Fold 7 vs Galaxy S25 Ultra expected differences:
Galaxy Z Fold 7 | Galaxy S25 Ultra |
---|---|
Might be as thin as the Ultra at 8.2 mm | 8.2 mm — a bit on the thick side by bar phone standards |
6.5-inch cover screen, but big 8-inch internal screen | Single, large 6.9-inch screen |
2,600 nits of peak brightness or more | 2,600 nits peak brightness Special anti-reflective coating |
Triple rear camera (200MP+12+10MP), 10MP external and 4MP internal selfie cameras | 200MP+50+10+50MP, 12MP selfie camera |

Design and Size
Origami vs Slab
The Galaxy S25 Ultra is your familiar heavyweight champion—an angular slab of glass and titanium, weighing in at 218 g, with that signature boxy silhouette. A 6.9-inch flat AMOLED up front and an S Pen tucked inside. Familiar yet fresh thanks to the boxy redesign from this year.
The Z Fold 7, though? That’s Samsung’s ultimate flex (literally). Rumors say it’ll slim down to a crazy-thin 8.2mm when folded, and shed a few grams down to 236g. To make it clear, the Galaxy S25 Ultra is 8.2mm right now — a bit thick by choco bar phone standards, but all forgiven because it’s packed with high-tier tech. If the Z Fold 7 is truly about that thin, that’d be a huge upgrade from before.
The Z Fold 7 outer screen’s getting wider, finally moving away from the “TV remote” dimensions of previous generations. And inside? An 8-inch foldable AMOLED screen, supposedly slightly wider than before, and ready to morph into your mini tablet.

---|---|
Thickness 4-6 mm unfolded 8.2-12.2 mm folded |
Thickness 8.2 mm |
Weight ~236 gr |
Weight 218 gr |
The Galaxy S25 Ultra is protected by Gorilla Armor on the front — a mix between Gorilla Glass Victus 2 and Samsung’s proprietary anti-reflecting coating on top. It’s very durable and resistant to those pesky micro-scratches that have a tendency to appear out of nowhere. We could hope for the cover screen of the Z Fold 7 to get the same anti-reflective treatment, but chances are low. More likely, it will be protected by a vanilla Victus 2.
For ingress protection, don’t expect the Galaxy Z Fold 7 to match the IP68 rating of the Galaxy S25 Ultra. IP48 is more probable — Samsung has achieved water protection by way of ancient black magic, we suppose. But particle resistance is limited to larger chunks of sand — the hinge will let super-fine dust in, so don’t bring it along for that camping trip.
Display Differences
Flat or flexible — take your pic
S25 Ultra: One large 6.8-inch QHD+ AMOLED, flat this time (no curves towards the edge), running 1-120 Hz adaptive refresh with 2,800+ nits of peak brightness. Samsung’s finest display for sure.
Fold 7: A much-improved 6.5-inch outer AMOLED, now actually usable, and a massive 8.0-inch internal screen that unfolds into tablet territory. Both at 120 Hz, for smooth animations and possibly the same peak brightness.

Performance and Software
Same brains, different bodies
Both phones should come with 12 GB of RAM, though the Fold might offer a 16 GB option for those who want to juggle five apps and a spreadsheet on that 8-inch screen.
Software-wise, we may — emphasis on may — get Android 16 with One UI 8 right out of the box, along with the full Galaxy AI suite: real-time translation, Circle to Search, live call summaries—the usual “AI but make it useful” features. And yes, both will enjoy Samsung’s 7 years of updates, which means both should last you well until 2032, so long as their batteries survive the trip.
Camera
The Fold finally catches up — almost
The Z Fold 7? It’s finally catching up, it seems. Rumors say it’ll borrow the 200MP main camera from the Ultra, which is a huge upgrade over the Fold 6. But the rest of the setup is still pretty modest: a 12 MP ultra-wide and 10 MP 3x zoom. It will most probably do fine. It just won’t be an outrageously over the top, “I have two zoom cameras” type of phone.

So if photography is your game, the Ultra is your racket, but the Fold 7 will hardly be considered a compromise. At least that’s what we expect if all the rumors come true.
Battery Life and Charging
Same story, different stamina
Supposedly, there will be no change — 25 W on the wire, 15 W wirelessly to top up that Galaxy Z Fold 7. The Galaxy S25 Ultra is at least a bit faster, with a 45 W power draw to charge its 5,000 mAh battery. Wirelessly, it also supports 15 W “almost” Qi2 charging (no magnets, thus the “almost”).

Summary
The Galaxy Z Fold 7? That’s for the multitaskers, the early adopters, the power users who want their phone to be a tablet and their tablet to be their phone. If it truly happens to be thin enough, light enough, and fast enough to be taken seriously, it may just draw in the last on-the-fencers to its side!
